The term fluids generally applies to:
solid and liquid
liquid and gas
solid and plasma
water only
Density is
the weight of a fixed mass of something
the volume of a fixed weight of something
the weight of a fixed volume of something
the mass of a fixed volume of something
To obtain the absolute pressure from the gauge pressure:
subtract atmospheric pressure
add atmospheric pressure
subtract 273
add 273
The vessels shown above all contain water to the same height. Rank them according to the pressure exerted by the water on the vessel bottoms, least to greatest.
1,2,3,4
3,4,2,1
4,3,2,1
2,3,4,1
All pressures are the same
This is the unit to measure Pressure
Newton
Pascal
cubic meter
square meter
Density is measured in
Newtons
Pascals
m3kg
Cubic meters
Pascal states that
Pressure is force per unit area
When velocity is higher, the pressure is lower
When force is applied, the pressure is transmitted equally through the fluid
Pressure transmitted is directly proportional to the force applied
Which object involving pascal principle
Why oil is the best fluid used in hydraulic system
Oil low density
Oil is incompressible
Oil low specific heat capacity
Oil is opaque
